A suitable clutch element 90 splined tothe transmission shaft and preferably controlled from the front end o the machine by means of shift/ing rod 92 and clutch engaging fingers 94 may be shifted into engagement with the gear 88 ,to drive the transmission shaft 95, which extends to the rear end of the machine andcarries spiral pinions 96 engaging spiral gears 98 `on the drive shafts of both forwarders. l l

y The cans are placed on the receiving table 99 by the operator and .rolled into the machine to be received by the front conveyor.

We have provided means for exposingV the cans as'they pass over each conveyor tothe action of a large number of powerful jets of cleansing fluid in the front tank'and to similar jets of rinsing and sterilizing fluid 1n the second tank. This means comprises pressure heads 100 located opposite each other on the sides of the tanks, each head provided in this instance with a set of nozzles 102 adjacent the front side of the head and preferably extending horizontally and at an angle rearwardly, in opposition tp the direction `of travel of the conveyor, another set of nozzles 104Yadjacent the rear edge of the head and directed horizontally and slightly forwardly, and a central. set of jets the lower jets 106 of which are directed horizontally and directly across the body of the machine, and the upper jets 108 of which are directed across the body of the machine and inclined somewhat downwardly. It will be seen that as each can passes between the opposed pressure heads, it will be heavily sprayed by jets coming from a large number of different directions completely cleansing every part of thesurface of the can. As illustrated in Fig. 1 at 110 and Fig. 5 at 112 the back of the plate 114 forming the frontv wall of the pressure head is preferably cast to present surfaces at its rea-r side perposition by a suitl v.pendicular to the direction in which the jet ioles areto be drilled. This greatly facilitates the drilling operation as the drill isf sideways.

Pi'voted doors jare pro'- vided 'which may be readilyy swung out of the way by engagement with the lcans as they passthrough the machine- Onedoor 128 is located at the entrance to prevent the fluid in the frontv tank splashing out of the machine, a second door 130 is -positioned at the end of the front conveyor to prevent the liquid in the front tank being thrown by the jets into the rear tank' and fvice versa, and a third' the rear end of the rear conveyor to prevent the contents of the rear tank being splashed out at the iear end of the body. As they reach the end of the treat" conveyor the articles assing through ,the machine. are subjectedp to the action of a steam ,jet located door 132 is positioned at j at 134 to completely sterilize and heat them afterwhich they'roll across a shortspace onto the drier 62. y L j The drier comprises va `'simple open top box 136 containing a coil of piping `138 to which live steam is delivered `under `high pressure. The articles come to rest on-this box and as soon as dry, may. beremoved. The steam jet 134 is 'preferably/fed from the discharge lend of the coil 138 and we also *l provide piping 139 for conveying steam from the same source to-two additional manually controlled valves 140 and 142 one posi'- tioned back of each tank. Steam may thus readily be delivered to any suitable noise` less steam heater (not shown) one of which may be located in each tank for heating the contents of the tank and maintaining it at proper temperature during the operation of the machine.

To facilitate cleaning or repairing the machine the top of the body is formed of a series of removable panels 144 upon removal pose comprises aremovable supporting bar i frame 30 and forwarder around the axis 'of the drive shaft 16. Before this is done the slats .V-and 54 arc removed from above the .forwarders and the support. for the front i end of each'forwarder'is disconnected from the supporting structure'of the tank. TheI connection we have provided for this pur- '146 see Fig. 8) extending through suitable end earings 148 carried by the walls 150 `of the body. IVhcnlthe `device is in use, lock nuts 152 are screwed-on the end of the supporting bar to clamp'it firmly in position as shown in Fig; 8. :To remove the bar l.the lock nuts are first unscrewed andthe threaded shank of an eyeletlli is screwedinto a threaded socket on the' end of the bar-so-that it may be readily pulled out, releasing'the frame 30 so .that it may be swung up out of `the way. Drainv cocks 156 areprovidedfor emptying the used `fluid .from the tanks and .we prefer. to em loy a spraypipe 158 in each-tank locate near the rear end of the i. tank, through lwhichby means of suitable f piping 160 and lvalves 162 water mav-be sprayed into Vthe empty tank to, flow down tate vthe cleaning of the machine.

. The eylindrical containers ordinarily emf ployed for lhandling bulk ice cream, and any and 54 in gentle contact wit 'other l containeror utensil having" an approximately cylindrical body ofl suiclent length to enable it to roll will be carried through the device on the sloping tracks the clips 44 acting as followers. lRubbing between the containers and the conveyors which rapidly wears the tin off the containers, is thus reduced to a minimum. It Will also be apparent that any other irregular shaped utensil such -asv a can cover or tray will slide through the machine with no more friction than it would be subjected to if drawn over any other sort of stationarytrack.

IVhile we have illustrated and described Iin detail the preferred embodiment of our invention. it` should be clearly understood that the disclosure is merely for purposes of illustrationl and thatvmany modifications and vvariations will naturallyx occur to those skilled in the art.
